I just get a can or two of Black Beans (seasoned or plain) and rinse them in a strainer and let drain. I spread them out on paper towels to dry a little more but don't stress that they are totally dry. Then put a little bit of olive oil in a big bowl, add the beans and shake until they are all coated. You can stir with a spoon but I don't want to break any of the beans. Then add whatever seasonings you want. I add A LOT of garlic powder and some kosher salt and shake. You can taste them raw and see what you think of the seasoning. Spread them on a baking sheet and put in the oven at about 400 for around 20-30 mins. I usually turn the oven off and leave them in there for about an hour to dry them more. Let cool and then put in a ziplock bag or sealed container
This is a really loosey goosey recipe. Use any type of beans you like-- you will find a lot of recipes for Roasted Chickpeas on the internet. Adapt them for any beans you like. Add what every seasonings you like. You can make them sweet or savory. Then use them any way you want. You can eat them straight out of the bag, use them as croutons to add that taste and crunch with no carbs in a salad or soup.
The bigger beans take longer to cook and I have found that leaving them in the turned off oven after the initial time adds that crunch, otherwise they are usually still soft in the middle. Also the black beans "pop" so the are UGLY! Don't let that dissuade you.
"A pint's a pound the world around."
16 oz of water weighs a pound. You eat breakfast and drink a cup of juice/water/coffee? You have a snack and a glass of water? You eat lunch? All of that is weight you are adding in to your body during the day and it will show up on the scale. Go to the bathroom and it will go down sometimes significantly depending on the circumstance

. Didn't eat and/or not drinking fluids? Did you just work out and sweat a lot? Dehydration will show a loss, sometimes pretty big. I weigh every morning--first thing, after I go to the bathroom and totally nakkie-- but you aren't really going to do anything but drive yourself insane if you weigh throughout the day. Especially if you weigh in the morning nakkie and then have clothes on later. If you are doing what you are supposed to and drinking your water and eating regular healthy meals then you SHOULD be adding 3-4 pounds during the day.
DD16 and I had breastfeeding problems. Since we had no idea how much milk she was getting I had to rent a very sensitive scale and we would weigh her right before we fed her and then immediately after with NO changes to her other than eating. If she had a dirty diaper it had to stay on because that weight was the same if it was inside of her or in her diaper. If a sock came off it had to go back on. We were able to see very clearly that she was only getting a few ounces of breastmilk at each feeding. Everything that goes in weighs something and will show up on the scale.
So drink your 4 pounds of water daily and know that you are absolutely helping the big picture.
